I am trying to make it easy for gnome software to be installed by novices using OLPC F11 installations ( http://wiki.laptop.org/go/Release_notes/10.1.3 )

In olpc F11 , double clicking in gnome to install an rpm is not working for me. 

Is there any way to go enable this double-click-to-install functionality in F11?  Or to make my rpm delivered via usb stick easy to install without terminal and rpm -i myCoolApp.rpm ?

Thanks!
